So what makes a good breeder?
To me, its understanding what you have in front of you and understanding it well through interaction for more than an hours training a day, through living with them.
Understanding what you are trying to acheive.
Not breeding dogs with known health issues, or temperament issues but only chosing the best available for your goals from the start, instead of trying to breed faults out. Start with out them if thats possible.
Balanced nutrition and enough of of it, with control of worms , fleas etc.
Health test or chose from clear by parentage when its known their is a good chance of problems occurring in a breed, but the ultimate goal should be thats its not nmeeded.
LOTS of socialisation of pups and getting to know them to form opinions on their character, then chosing homes to match to the best of your ability .Making sure before the mating takes place that there IS be a demand for what you expect to offer.
Follow up on pups to see if they have matched your and the buyers expectations. To try to determine if your breeding has has been successful or not before you repeat it, or find if changes are needed.
Chose homes very carefully and try to match suitability.
Understanding and adhering to legal obligations
I prefer to buy from a breeder who keeps their dogs as family members 1st. Whos dogs are known and proven reliable in the environment they are bred to live in.
I do NOT want to buy from a breeder who sets out conditions of sale. If you do not think I am a responsible owner, why the hell would you sell me a dog?
If I buy a dog, I am taking full responsibility for it. As should any buyer. Unless you are shown to have been negligent in breeding dogs that should never have been bred, the risks and responsibility for dealing with problems are are mine, tho' your availability to consult with is only fair.
I don't believe a breeder should HAVE to take back any dog...... But I do believe they should insist on involvement in re homing suitably if they can't.
Circumstances can make taking a dog back impossible.
Last but not least, I think a good breeder is well aware that in bringing these lives into the world, they do bear some responsibility for the lives those dogs will live and do their best to make sure sure they will be happy and fulfilling lives, to the best of their ability.
I am not against profit. It can be the mark of a successfull breeder. I AM against commercial breeding because a commercial breeding dog is NOT living the happy and fullfilled life it was bred for and all dogs should expect. They won't all acheive it, but neither will we humans.
